Description

Die Erfindung betrifft Schließzylinder mit einem Gehäuse und einem darin verdrehbaren, ein oder mehrere Magnetrotoren tragenden Kern, wobei im Kern zumindest ein axial verschiebbares Sperrelement vorgesehen ist, dessen Verschiebbarkeit durch die Magnetrotoren gesteuert ist und das Sperrelement nach außen ragende Sperrfortsätze aufweist, das Gehäuse an der Innenwand angeordnete Gehäuselängsnuten und Ringnuten aufweist, wobei die Ringnuten in einer solchen axialen Lage angeordnet sind, daß in verschobener Stellung des Sperrelementes, in der nach innen ragende Abtastelemente in Ausnehmungen der Magnetrotoren liegen, eine Freigabe für die nach außen ragenden Sperrfortsätze beim Verdiehen des Kerns gegeben ist.The invention relates to locking cylinders with a housing and a core rotatable therein and carrying one or more magnetic rotors, wherein at least one axially displaceable locking element is provided in the core, the displaceability of which is controlled by the magnetic rotors and the locking element has outwardly extending locking projections, the housing on the Internal longitudinal housing grooves and annular grooves arranged, the annular grooves being arranged in such an axial position that in the displaced position of the locking element, in which inwardly projecting scanning elements lie in recesses of the magnetic rotors, there is a release for the outwardly projecting locking projections when the core is distorted is.

Die obengenannten Schließzylinder sind Stand der Technik und z.B. in der AT-PS 357 430 beschrieben. Gegenüber diesen bekannten Konstruktionen stellt sich die Aufgabe, die auf die Magnetrotoren bei Fehlsperrungen wirkenden Kräfte noch weiter herabzusetzen, um etwaige Beschädigungen der Magnetrotoren sicher zu vermeiden und die Abtastelemente für die Magnetrotoren geringer dimensionieren zu können, um damit die mechanische Genauigkeit zu erhöhen. Weiters stellte sich die Aufgabe, die Einwirkung von Umwelteinflüssen, wie Witterung, Staub, aggressive Stoffe, sowohl auf den Rastring als auch auf die im Inneren des Zylinderkernes befindlichen beweglichen Teile noch weiter zu verringern.The above locking cylinders are state of the art and e.g. in AT-PS 357 430. Compared to these known constructions, there is the task of further reducing the forces acting on the magnet rotors in the event of incorrect locking in order to reliably avoid any damage to the magnet rotors and to be able to dimension the scanning elements for the magnet rotors smaller, in order to increase the mechanical accuracy. Furthermore, there was the task of further reducing the influence of environmental influences, such as weather, dust, aggressive substances, both on the locking ring and on the moving parts located inside the cylinder core.

Gemäß vorliegender Erfindung werden die gestellten Aufgaben dadurch gelöst, daß das Sperrelement einen Abtastschieber mit zu den Magnetrotoren ragenden Abtastelementen und einen die Sperrfortsätze tragenden, mit dem Abtastschieber kraftschlüssig verbundenen Sperrschieber umfaßt, und daß ein gehäusefest angeordneter Steuerfortsatz vorgesehen ist, durch den das Sperrelement bei 0-Stellung des Zylinderkernes gegen die Kraft einer am Sperrelement angreifenden Feder in Sperrstellung gehalten und bei Verdrehen des Kernes in Freigabestellung verschoben ist. Weiters sind gemäß Erfindung der Sperrschieber und der Abtastschieber in einem den Zylinderkern abschließenden Kerndeckel angeordnet,und der Abtastschieber und der Sperrschieber sind über zumindest einen durch eine Öffnung des Kerndeckels hindurchragenden Mitnehmer miteinander verbunden. Nach einem weiteren Kennzeichen der Erfindung ist im Bereich der Öffnung zwischen Kerndeckel und Sperrschieber oder Abtastschieber eine Dichtung vorgesehen. Fernerhin ist die Erfindung dadurch gekennzeichnet, daß der Steuerfortsatz an einem in das Gehäuse drehfest einsetzbaren Steuerring ausgebildet ist und daß der Kerndeckel für den Abtastschieber und/oder den Sperrschieber Führungen aufweist.According to the present invention, the objects are achieved in that the locking element comprises a scanning slide with scanning elements projecting to the magnet rotors and a locking slide carrying the locking extensions and non-positively connected to the scanning slide, and in that a control extension arranged fixed to the housing is provided, through which the locking element at 0 -Position of the cylinder core against the force of one the spring engaging the locking element is held in the locking position and is displaced when the core is rotated into the release position. Furthermore, according to the invention, the locking slide and the scanning slide are arranged in a core cover closing the cylinder core, and the scanning slide and the locking slide are connected to one another via at least one driver projecting through an opening in the core cover. According to a further feature of the invention, a seal is provided in the area of the opening between the core cover and the locking slide or scanning slide. Furthermore, the invention is characterized in that the control extension is formed on a control ring which can be inserted non-rotatably into the housing and in that the core cover has guides for the scanning slide and / or the locking slide.

Im folgenden wird die Erfindung anhand der Zeichnungen beispielhaft erklärt. Fig. 1 stellt schematisch einen teilweisen Schnitt durch ein erfindungsgemäßes Zylinderschloß dar, wobei der Schnitt in der Ebene der Achsen der Magnetrotoren liegt, siehe dazu die Schnittlinie I-I in Fig. 2. Fig. 2 ist eine Aufsicht auf den Schließzylinder gemäß Pfeil II in Fig. 1, wobei das Zylindergehäuse aufgebrochen dargestellt ist.In the following the invention is explained by way of example with reference to the drawings. 1 schematically shows a partial section through a cylinder lock according to the invention, the section lying in the plane of the axes of the magnet rotors, see section line II in FIG. 2. FIG. 2 is a plan view of the locking cylinder according to arrow II in FIG 1, the cylinder housing being shown broken away.

Der Grundaufbau des erfindungsgemäßen Schließzylinders ist ähnlich jenem der AT-PS 357 430. Im Zylinderkern 1 ist parallel zum Schlüsselkanal 2 eine Ausnehmung 3 angeordnet, in der die Magnetrotoren 4 frei rotierbar angeordnet sind. Durch Einschieben eines richtigen Schlüssels 25 (in Fig. 1 abgebrochen dargestellt) werden die Magnetrotoren 4 in die in Fig. 1 dargestellte Lage gebracht, wobei also die Ausnehmungen 5 der Magnetrotoren derart ausgerichtet sind, daß Abtastelemente 6 eines Sperrelementes 22 axial verschoben werden und in die Ausnehmungen 5 eintreten können.The basic structure of the locking cylinder according to the invention is similar to that of AT-PS 357 430. In the cylinder core 1, a recess 3 is arranged parallel to the key channel 2, in which the magnet rotors 4 are freely rotatable. By inserting a correct key 25 (shown broken off in FIG. 1), the magnet rotors 4 are brought into the position shown in FIG. 1, so that the recesses 5 of the magnet rotors are oriented such that scanning elements 6 of a locking element 22 are axially displaced and in the recesses 5 can occur.

Bekannte Sperrelemente der beschriebenen Art waren einstückig und übernahmen sowohl die Funktion des Abtastens der Stellung der Drehzuhaltungen als auch die Funktion des Sperrens des Schließzylinders gegen Verdrehen. Demgegenüber umfaßt das Sperrelement 22 gemäß vorliegender Erfindung einen Abtastschieber 7 und einen Sperrschieber 10.Known locking elements of the type described were in one piece and took on both the function of scanning the position of the rotary tumblers and the function of locking the locking cylinder against rotation. In contrast, the blocking element 22 according to the present invention comprises a scanning slide 7 and a blocking slide 10.

Der Äbtastschieber 7 liegt den Drehzuhaltungen 4 gegenüber und weist Abtastelemente 6 auf. An der anderen Seite des Abtastschiebers ist ein Mitnehmer 8 vorgesehen. Dieser Mitnehmer greift in eine Ausnehmung 9 des Sperrschiebers 10 ein, wodurch die beiden Schieber kraftschlüssig miteinander verbunden sind. Zwischen den beiden genannten Schiebern ist ein Kerndeckel 11 angeordnet, der in der Ausnehmung 3 im Kern 1 dicht eingesetzt ist. Für die Bewegung des Mitnehmers 8 weist der Kerndeckel 11 einen Schlitz 12 auf. Zur Abdichtung dieses Schlitzes 12 nach außen hin ist zwischen dem Sperrschieber 10 und dem Kerndeckel 11 noch eine Dichtungsplatte 13 angeordnet, die sich mit dem Mitnehmer 8 auf dem Kerndeckel 11 verschieben läßt.The Äbtastschieber 7 is opposite the rotary tumblers 4 and has Ab probe elements 6. A driver 8 is provided on the other side of the scanning slide. This driver engages in a recess 9 of the locking slide 10, whereby the two slides are non-positively connected. A core cover 11 is arranged between the two mentioned slides and is inserted tightly in the recess 3 in the core 1. For the movement of the driver 8, the core cover 11 has a slot 12. To seal this slot 12 to the outside, a sealing plate 13 is arranged between the locking slide 10 and the core cover 11, which can be moved with the driver 8 on the core cover 11.

Der Sperrschieber 10 weist an seiner Oberfläche die Sperrfortsätze 14 auf, die in bekannter Weise bei 0-Stellung des Schließzylinders in einer axialen Nut 23 des Zylindergehäuses 24 angeordnet sind und so axial mit dem Sperrschieber verschoben werden können. Nimmt der Sperrschieber 10 eine solche axiale Lage ein, daß die Sperrfortsätze 14 mit den zugehörigen Ringkanälen 15 des Zylinderkernes fluchten, kann der Zylinderkern verdreht und das zugehörige Schloß betätigt werden.The locking slide 10 has on its surface the locking extensions 14, which are arranged in a known manner in the 0 position of the locking cylinder in an axial groove 23 of the cylinder housing 24 and can thus be axially displaced with the locking slide. If the locking slide 10 assumes an axial position such that the locking extensions 14 are aligned with the associated ring channels 15 of the cylinder core, the cylinder core can be rotated and the associated lock can be actuated.

Wie in den Fig. 1 und 2 ersichtlich, steht das ganze Sperrelement 22, bestehend aus dem Abtastschieber und dem Sperrschieber, unter dem Druck der Druckfeder 16. Das Sperrelement ist also so vorgespannt, daß die Abtastelemente 6 in Richtung zu den jeweils zugehörigen Drehzuhaltungen 4 geschoben werden. Die axiale Verschiebung des Sperrelementes 22 wird durch einen Steuerring 17 gesteuert. Der Steuerring ist mit dem Gehäuse drehfest verbunden und weist einen Steuerfortsatz 18 auf.As can be seen in FIGS. 1 and 2, the entire locking element 22, consisting of the scanning slide and the locking slide, is under the pressure of the compression spring 16. The locking element is thus preloaded in such a way that the scanning elements 6 move in the direction of the associated rotary tumblers 4 be pushed. The axial displacement of the locking element 22 is controlled by a control ring 17. The control ring is non-rotatably connected to the housing and has a control extension 18.

Bei der in Fig. 1 und 2 dargestellten Stellung des Zylinderkernes steht der Steuerfortsatz 18 der Steuernase 19 des Sperrschiebers 10 gegenüber, und das gesamte Sperrelement ist dadurch in die linke Lage gegen die Kraft der Feder 16 gerückt. Die Abtastelemente 6 sind außer Eingriff mit den Drehzuhaltungen 4.In the position of the cylinder core shown in FIGS. 1 and 2, the control extension 18 faces the control lug 19 of the locking slide 10, and the entire locking element is thereby moved into the left position against the force of the spring 16. The scanning elements 6 are disengaged from the rotary tumblers 4.

Wird in den Schlüsselkanal 2 der richtige Schlüssel 25 eingeschoben, sodaß die Magnetrotoren zufolge der Schlüsselmagnete 26 die in Fig. 1 eingezeichnete Lage einnehmen, und wird mit dem Schlüssel der Zylinderkern 1 etwas verdreht, läuft die Steuernase den Steuerfortsatz 18 hinunter (siehe Fig. 2), und das Sperrelement wird durch die Kraft der Feder 16 nach rechts gerückt, wobei die Abtastelemente 6 in die Ausnehmungen 5 der Magnetrotoren 4 hineingeschoben werden. Durch diese Verschiebung gelangen die Sperrfortsätze 14 in die richtige Lage, um innerhalb der Ringkanäle 15 Platz zu finden, sodaß die Drehung des Zylinderkernes ermöglicht ist.If the correct key 25 is inserted into the key channel 2, so that the magnet rotors, as a result of the key magnets 26, assume the position shown in FIG. 1, and if the key of the cylinder core 1 is rotated somewhat, the control nose runs the control extension 18 down (see Fig. 2), and the locking element is moved to the right by the force of the spring 16, wherein the scanning elements 6 are pushed into the recesses 5 of the magnet rotors 4. As a result of this displacement, the locking extensions 14 come into the correct position in order to find space within the ring channels 15, so that the rotation of the cylinder core is made possible.

Wenn ein falscher Schlüssel eingesteckt wird, so nimmt mindestens einer der Magnetrotoren 4 eine Drehlage ein, bei der die zugehörige Ausnehmung 5 nicht dem Abtastelement 6 gegenübersteht. Bei einem Verdrehen des Zylinderkernes stößt jeweils das Abtastelement 6 gegen die Umfläche 20 des Magnetrotors, wodurch ein weiteres Verschieben des gesamten Sperrelementes verhindert ist. Dadurch können die Sperrfortsätze 14 nicht mit den Ringkanälen 15 fluchten, sondern kommen an den Rastflächen 21 der axialen Nut 23 zu liegen, wobei die Rastflächen 21 durch die verbleibenden Stege zwischen den Ringkanälen 15 gebildet sind.If an incorrect key is inserted, at least one of the magnet rotors 4 assumes a rotational position in which the associated recess 5 does not face the scanning element 6. When the cylinder core is rotated, the scanning element 6 abuts against the circumferential surface 20 of the magnetic rotor, thereby preventing the entire blocking element from moving further. As a result, the locking extensions 14 cannot align with the annular channels 15, but come to rest on the latching surfaces 21 of the axial groove 23, the latching surfaces 21 being formed by the remaining webs between the annular channels 15.

Die auf die Magnetrotoren 4 über die Abtastelemente 6 wirkenden Kräfte können nur so groß sein, wie die Kraft der Feder 16 ist. Diese Kraft ist völlig unabhängig von den aufgewendeten Drehkräften vom Schlüssel her und muß nur so stark bemessen sein, daß ein einwandfreies Verschieben des Abtastschiebers 7 gewährleistet ist. Dadurch ist eine Beschädigung der Magnetrotoren oder des Steuerringes ausgeschlossen. Die Teile des Abtastschiebers können sehr schwach dimensioniert sein, und auch die zugehörigen abzutastenden Teile der Magnetrotoren müssen nur geringe Kräfte aufnehmen. Demgegenüber ist der Sperrschieber 10 massiv ausgebildet und kann hohe, über den Schlüssel aufgewendete Drehkräfte aufnehmen, ohne diese Drehkräfte auf den Abtastschieber zu übertragen.The forces acting on the magnet rotors 4 via the scanning elements 6 can only be as large as the force of the spring 16. This force is completely independent of the turning forces exerted by the key and only has to be dimensioned to such an extent that correct displacement of the scanning slide 7 is ensured. This prevents damage to the magnet rotors or the control ring. The parts of the scanning slide can be of very weak dimensions, and the associated parts of the magnetic rotors to be scanned also have to absorb only small forces. In contrast, the locking slide 10 is solid and can absorb high turning forces applied by the key without transmitting these turning forces to the scanning slide.

Durch den dichten Sitz des Kerndeckels 11 wird das empfindliche Innere des Schließzylinders zuverlässig gegen Staub, Dämpfe, Feuchtigkeit etc. geschützt.Due to the tight fit of the core cover 11, the sensitive interior of the lock cylinder is reliably protected against dust, vapors, moisture, etc.

In den Fig. 1 und 2 ist der Steuerring am bundseitigen Ende des Gehäuses angeordnet, also auf jener Seite, von der der Schlüssel in das Schloß eingesteckt wird. Die ganze Anordnung kann aber auch umgekehrt im Schloß angeordnet sein, sodaß dann der Steuerring am kupplungsseitigen Ende sitzt. Der Steuerring 17 kann auch einstückig mit dem Gehäuse sein, oder es wird nur der Steuerfortsatz 18 in das Gehäuse als getrennter Bauteil eingesetzt.1 and 2, the control ring is arranged at the flange end of the housing, that is to say on the side from which the key is inserted into the lock. The whole arrangement can also be reversed in the lock, so that the control ring on the clutch side End sits. The control ring 17 can also be in one piece with the housing, or only the control extension 18 is inserted into the housing as a separate component.

In Fig. 1 ist die Magnetrotorenkonstruktion mit Sperrelement nur auf einer Seite des Zylinderkernes eingezeichnet. Symmetrisch dazu kann auch auf der anderen Seite des Schlosses eine gleichartige Konstruktion angeordnet sein, wodurch die Variationszahlen und die aufzunehmenden Sperrkräfte erhöht werden.In Fig. 1, the magnet rotor construction with locking element is shown only on one side of the cylinder core. Symmetrically to this, a similar construction can also be arranged on the other side of the lock, as a result of which the number of variations and the blocking forces to be absorbed are increased.

Der Kerndeckel 11 kann aus Kunststoff oder aus Metall angefertigt sein. Für größtmögliche Abdichtwirkung ist es vorteilhaft, wenn der Kerndeckel im Preßsitz in der Ausnehmung 3 sitzt. Zur exakten Führung des Abtastschiebers und Sperrschiebers weist der Kerndeckel zu beiden Seiten erhöhte Ränder 27, 28 auf, die die Führung in Verschieberichtung bewirken.The core cover 11 can be made of plastic or metal. For the greatest possible sealing effect, it is advantageous if the core cover sits in a press fit in the recess 3. For exact guidance of the scanning slide and locking slide, the core cover has raised edges 27, 28 on both sides, which effect the guidance in the direction of displacement.
